Objectives


Much of electronic engineering practice involves the design, analysis and measurement
of electrical circuits and their characteristics. This course introduces students

to, and
reinforces knowledge of, a broad range of common electrical networks encountered in
engineering practice. In addition, the foundations are laid for future studies in analog
electronics and telecommunications. The course has an emphasis on labora
tory and
problem solving skills as well as the underlying principles.

During the course, opportunities will be given to develop a range of generic skills
including written communication skills, problem solving skills and analysis and critical
evaluation sk
ills.

Students will also have the opportunity to practice and enhance their ability to work
effectively as a member of a team and to assume responsibility and make decisions.

Links with other Courses in the Program


Given that much of electronic engineering practice involves the design, analysis and

measurement of electrical circuits and their characteristics, there is a need for a
thorough understanding of such circuits. The circuit theory from this course provides a
basis for second semester studies in “Signals and Systems” and in “Analog Electron
ics”.
Future studies in telecommunications will depend on the introduction to
electromagnetic wave theory from this course. Measurement skills reinforced in the
course will be used in most later courses in the program.

Brief Description


This course

deals with the basic principles of linear and non
-
linear network theory and
provides an introduction to circuit and system design and to communications. The use
of analysis tools, such as
WinPspice
, is also introduced. Assessment is by Laboratory
Work,

Laboratory Reports, Computer Based tests, and Examinations.

Content


As much of electronic engineering practice involves the design, analysis and
measurement of electrical circuits and their characteristics, a sound development of
these principles is

very important for an electronic engineer. Analysis is usually
performed with the aid of computer packages. The industry standard
WinPSpice

is
introduced through tutorial and assignment work.


The course starts with a revision of electrostatics and magn
etostatics. This leads to the
development of Maxwell’s equations and an introduction to electromagnetic wave
theory. A thorough revision of DC circuits, as introduced in “Physics and
Instrumentation”, leads to basic circuit theorems. These are then exte
nded to AC
circuits, first through vector and phasor methods and then from complex analysis.


A complementary laboratory program develops measurement, analysis and design
skills. Commencing with a simple DC circuits, complexity is gradually introduced
c
ulminating in the measurement of AC filter characteristics.

Notes

(1)

To be eligible for a passing grade in this course, students are required to:
Submit ALL assessment items, Attend all laboratories, Submit passing
laboratory report
s, Pass the Module A
WinPSpice

Assignment, Pass each of the
Module Tests B, C, D and E, Submit passing Computer Based Questions, and
obtain a minimum overall mark of 50%.

Any laboratory report, or assignment, that receives a failing grade must be
improved
upon, and then resubmitted. The maximum grade for a resubmitted
assessment item is a Pass (nominally 50%), and an assessment item must be
resubmitted until a pass grade is obtained.

Note for any re
-
submitted work, ALL questions / sections must be attempte
d,
and there must be a reasonable level of work done for the attempt. That is, a re
-
submission that is only ‘partly done’ will NOT be accepted.


(2)

WinPSpice

Assignment presentation

Students will be allocated to small groups of approximately 4 students e
ach for
their
WinPSpice

assignment. Each student will be allocated to a specific subtask
within the overall group task, the subtasks being organised so that they are
essentially independent of each other but they share a common theme.

Each student team wi
ll be required to give a 15 minute oral presentation on their
work so far (preferably with a demonstration of working programs). The first
speaker will introduce the overall task as well as reporting on their individual
task. The final speaker will repor
ting on their individual task, and then
summarise the overall task.

The team will be assessed on the technical aspects, fluency, and presentation
ability. The individual student will receive the result assigned to the group.

Presentation assessment will

be by staff and students involved in the course.


(3)

Group
WinPSpice

Assignment report

The report will firstly, contain an introductory section that will be common to
the team. Next each team member will prepare and an individual report section
on their

given topic, that describes their overall task and includes ALL
WinPSpice

diagrams, inputs and outputs. Finally an overall discussion and
conclusion will be given.

Module Tests B, C, D and E Marks

There are closed book tests for Modules B, C, D and
E. The questions will be a
combination of problem solving and short answer. The test will normally be
scheduled for the first lecture of the week following the completion of the Units
covered by the Test. Confirmation will be given during the last lectu
re of a Unit
as to when the test will be held.


Students who do not achieve a passing mark in a Module Test will be offered the
opportunity to resit the assessment for the Module. Resits of Module Tests will
most likely be scheduled on Friday evenings.
The course notice board on
Learning@Griffith

should be consulted regularly for information on “Resits”.

The maximum mark achievable for a resit is 50%, awarded if the student
achieves a 50% or better standard on a resit test.


(5)

Laboratory reports

There
are weekly laboratory activities for the first 10 weeks. Every second week
a report is due on the activities carried out during the previous two weeks. The
report is due for submission at the beginning of the laboratory class of the
following week.


(6)

Computer Based Questions

Self assessment questions from the lecturer’s computer package,
‘CircuitTester’

are required for submission each week. The criteria for submission is provided
in the Laboratory Manual.



12

Rationale for Assessment


The problem qu
estion assessment is designed to encourage students to develop a solid
understanding of the concepts being covered in the lecture sessions. Students are
required to hand
-
in each week a set problem exercise.

The assignments are set to develop
WinPSpice

ski
lls as well as team working skills.
Students will be allocated to groups of 4
-
5 for their assignment task. The set topics will
be chosen to bring together various topics covered in the tutorial sessions as well as
material introduced in the lectures and
laboratory classes.


A 15 minute group seminar presentation is part of the assessment of the
WinPSpice

assignments.

The laboratory reports are to encourage the students to practice the skills of technical
report writing and to bring together various topics

covered in the lecture, tutorial and
laboratory sessions.

The Module Tests will test the students' understanding and knowledge of the range of
topics covered in the course.

eport including any calculations, graphs, discussion and conclusion
should be the sole work of the student submitting.

For the WinPspice assignment, whereas the introduction will be common to the team,
the written report including the detailed analysis and

design, any calculations, graphs,
discussion and conclusion should be the sole work of the student submitting. Students
will be offered a choice of assignment topic. These choices will be displayed on the
course website. By the end of week 3, students
are required to nominate their preferred
individual topic. As topics are grouped together into team tasks, the choice of topic will
determine the team composition.
